1918. Timid and shy Emmaline Balakin lives more in books than her own life. That is, until an envelope crosses her desk at the Dead Letter Office bearing a name from her past, and Emmaline decides to finally embark on an adventure of her own as a volunteer librarian on the frontlines in France. But when a romance blooms as she secretly participates in a book club for censored books, Emmaline will need to find more courage within herself than she ever thought possible in order to survive.
